Gestão participativa em educação: compasso e descompasso de uma experiência de democracia no espaço escolar

This work aims at investigating the strategies of management used by State School Joaquim Jose de Medeiros, located in the city of Cruzeta - RN, as award practice of "School of Reference in Management", with a state title in 1999 at the beginning of the decade from 2000, being "Outstanding Brazil" from best management strategies nationally. In 2005, it is ranked among the best experiences of the state. It has been become complex by experiencing in that institution, but at the same time an enjoyable practice, mainly by using a social research, in a qualitative and quantitative approach, and a analysis of the institutional performance of two management practices: from 1995 to 2002 and from 2003 to 2007 . To understand the object, a investigative questionnaire was used with representatives of the school community and carried out an analysis of assessment of institutional and documents of institutional organization of the periods above in order to identify management strategies and examine the influences of the share capital, public policies , the institutional evaluation, in the process of democratic construction that has allowed achievements, highlighting Cruzeta, in the Seridó in the state of Rio Grande do Norte, semi-arid northeast, in the national and international juncture of well-successful experiences in management in institutional categories and leadership. This study becomes relevant to allow understand that the cultural practices of seridoenses that symbolize a capital generated by principles of trust, reciprocity, civic culture, as a driving force in overcoming the problems community and the conquest of democratic principles, worked for the school become a national reference in educational administration. Another aspect that made it natural that school was the collective creation of educational project with the participation and civic culture of self-evaluation as a way to understand the institutional practice and establish guidelines to improve the teaching and practice management in its many dimensions educational, social, administrative - financial and legal

Bolton freeware: aplicativo de avaliação de discrepância de massa dentária desenvolvido pelo programa de pós-graduação em odontologia/UFRN

The calculation of tooth mass discrepancy, essential for good planning and a proper orthodontic finishing, when performed manually, besides being laborious, requires considerable time consumption. The aim of this study was to develop and test Bolton Freeware, a software for analysis of the tooth mass discrepancy of Bolton, aiming to minimize the consumption of time in a less onerous way. The digital analysis of the software was done by means of two-dimensional scanning of plaster study models and compared to manual evaluation (gold standard), using 75 pairs of stone plaster study models divided into two groups according to the magnitude of the Curve of Spee (group I from 0 to 2 mm, group II greater than 2 to 3mm). All the models had permanent dentition and were in perfect condition. The manual evaluation was performed with a digital caliper and a calculator, and the time required to perform the analysis for both methods was recorded and compared. In addition, the software was evaluated by orthodontists regarding its use, by means of questionnaires developed specifically for this purpose. Calibration was performed prior to manual analysis, and excellent levels of inter-rater agreement were achieved, with ICC > 0.75 and r > 0.9 for total and anterior proportion. It was observed in the evaluation of error of the digital method that some teeth showed a significant systematic error, being the highest measured at 0.08 mm. The analysis of total tooth mass discrepancy performed by Bolton Freeware, for those cases in which the curve of Spee is mild and moderate, differ from manual analysis, on average, 0.09 mm and 0.07 mm respectively, for each tooth evaluated, with r> 0, 8 for total and anterior proportion. According to the specificity and sensitivity test, Bolton Freeware has an improved ability to detect true negatives, i.e. the presence of discrepancy. The Bolton analysis digitally performed was faster, with an average difference of time consumed to perform the analysis of Bolton between the two methods of approximately 6 minutes. Most experts interviewed (93%) approved the usability of the software
